Did You Know...
...that the inventor of the electric motor was a blacksmith named Thomas Davenport? Described as "a brilliantly unsuccessful inventor", Davenport invented the first rotary electric motor. In 1836 he headed out -- on foot -- from his Vermont home to file a patent application at the Patent Office in Washington, D.C. By the time he got there, he had squandered away his money and couldn't afford the $30 filing fee so he turned around and went home. When he later mailed in his application with money he'd raised, the Patent office was destroyed in a fire. He did finally get credit for his invention on Feb. 5, 1837.

It does not account for terminal disclaimers, term adjustments, failure to pay maintenance fees, or other factors which might affect the term of a patent.AbstractThe present invention describes a method for transmitting high bandwidth network content on a low bandwidth communications channel during off peak hours. According to one embodiment of the present invention, criteria is determined for downloading data from the communications channel and the data is downloaded from the communications channel during off-peak hours based on the determined criteria. According to another embodiment, a method for coordinated multicasts on a network is described. Download requests are received on a server from a plurality of clients on the network and stored on the server for the coordinated multicast. The coordinated multicast is generated at a predetermined time and then broadcast from the server to the plurality of clients at the predetermined time.Other References
